ARCH-BAR Foe CULTIVATORS.

SPECIFICATION forming part of Letters Patent No. 719,1 59, dated January27, 1903. Application filed July 10, 1902. Serial No. 115,084. (Nomodel.)

To a whom it may concern:

Be it known that I, OALE M. SULLINS, a citi- Zen of the United States,residing at Moody, in the county of McLennan and State of Texas, haveinvented a new and useful Arch-Bar for Cultivators, of which thefollowing is a specification.

My invention relates to an improvement in double cultivators, andparticularly with reference to the construction of the arch-bar whichconnects the respective cultivator-rigs together, the object of myinvention being to provide an arch-bar which is adapted for use not onlyfor connecting the cultivatorrigs together, but also for adjusting themlaterally toward and from each other as required by the width of thespaces between the rows and for securing the cultivator-rigs at anydesired adjustment.

A further object of my invention is to provide improved means forsupporting the archbar in an upright position, which supporting means isdetachable from the arch -bar, so that the latter may be readily appliedto and a5 detached from a double cultivator of any of the usual forms.

My invention consists in the peculiar construction and combination ofdevices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a doublecultivator provided with my improved arch-bar and adj usting-lever. Fig.2 is a detail front elevation of my improved arch-bar, showing also theadjusting-lever with which the same is provided. Fig. 3 is a detailvertical central sectional view of the same. Fig. 4 is a detailsectional view of the same, on a somewhat larger scale, taken on a planeindicated by the line a: 00 of Fig. 2.

In the embodiment of my invention here shown the arch-bar comprises twomembers 1 2, which are provided, respectively, at their upper ends withcurved or sector arms 3 4, that 5 overlap each other. Each of the saidcurved arms is provided with a sector-shaped slot 5 of suitable lengthand width, and the respective curved arms of the members 1 2 areslidably connected together by bolts 6, which operate in the slots 5. Onthe shanks of the said bolts within the said slots areantifriction-rollers 7. It will be understood that by thus slidablyconnecting the curved arms of the respective members 1 2 together thelatter may be so adjusted as to increase or diminish the distancebetween their lower ends, which are here shown as provided with hooks 8,adapted to engage suitable eyebolts or other similar devices a on thecultivator-rigs b of a double cultivator. Thereby the arch-bar may be sodisposed as to connect the cultivatorrigs together, and by adjusting therespective members of the arch-bar the cultivatorrigs may be movedlaterally toward or from each other, so that they may be disposed at anydesired distance apart, according to the width of the space between therows of plants. Each of the sector-arms of the arch-bar is provided onits upper side with a rack 9. The teeth of the respective racks areadapted to register with each other. Ahand-lever 10 is pivoted at asuitable distance from its lower end to the sector-arm of one of thearch-bar members, as at 11. As here shown, the pivot of the lever is inthe sector-arm 4 and the lower end of the lever is connected to themember 1 by a link 12. Hence the lever is pivotally connected to onemember of the arch-bar and connected by a link. to the other memberthereof; but within the scope of the appended claims this may bemodified, and I do not desire to limit myself in this particular. On thefront side of the lever near its lower end is a keeper 13, which bearsagainst the front side of the sector-arm 3 of the memher 1. This keeperis here shown as secured to the lever by a bolt 14 and also by aneyebolt 15, the eye 16 of which latter bolt is on the front side of thelever. The latter is also provided with a keeper 17, in which is alock9o ing bolt or dog 18, adapted to engage the racks 9, and thereby lockthe respective sec tions or members of the arch-bar together. A spring19 is here shown to normally keep said locking bolt or dog in engagementwith 9 5 the racks of the sectors, and the hand-lever 10 is shown asprovided with a thumb-lever 20, connected to the bolt or dog by a rod21, whereby the bolt or dog may be readily disengaged from the racks ofthe sector-arms to permit adjustment of the members of the arch-bar bymeans of the lever 10.

It will be observed by reference to Fig. l of the drawings that thehand-lever 10 is disposed in front of the drivers seat 0, where it iswithin convenient reach of the driver. It will be also understood thatby first releasing the dog or bolt 18 from the racks 9 and thenoperating the hand-lever the members of the arch-bar may be so adjustedas to set the cultivator-rigs at the required distance apart and thatthis adjustment may be effected without the necessity of stopping thecultivator if it is in motion and without dismounting therefrom.

To support the arch-bar in the required upright position, I haveprovided a hook-link 22, which may be attached to the rear end of thetongue or to any other appropriate portion of the sulky-frame and alsoengaged with the eyebolt 15. This hook-link may be readily disengagedfrom the eyebolt when it is desired to detach the arch-bar from thecultivator.

I. would have it understood that my improved arch-bar andoperating-lever may be used in connection with a double cultivator orsulky-cultivator of any appropriate form, and I do not desire to limitmyself in this particular.

Having thus described my invention, I claim- 1. An arch-bar forcultivators comprising a pairof members having curved portions formingsectors overlapping one another connected slidably and provided withteeth adapted to be brought into alinement, in combination with meansfor engaging said teeth of both sectors and thereby restrain the latterfrom movement with relation to each other.

2. An arch-bar for cultivators comprising a pair of members havingsectors overlapping one another, said sectors being provided, each witha slot and with a bolt engaging the slot of the opposite sector,friction-rollers upon said bolts and means for effecting the adj ustmentof the members of the arch-bar with relation to each other and forretaining them at the desired point of adjustment.

3. An arch-bar for cultivators,comprisinga pair of members havingtoothed sectors overlapping one another and slidably connected together,in combination with a lever having pivotal connection with one of saidsectors, a link connecting said lever with the arch member having theother sector and means carried by said lever to engage the teeth of thesectors when brought into alinement with each other.

4:. An arch-bar for cultivators,'comprisinga pair of members connectedtogether for angular adjustment, in combination with a lever secured toone of said members and a connection between the lever and the othermember, substantially as described.

5. An arch-barfor cultivators,comprisinga pair of members connectedtogether for angular adjustment, in combination with a lever secured toone of said members and a link connecting the lever with the othermember, substantially as described.

6. In a sulky-cultivator, the combination of an arch-bar having a pairof members connected to the respective cultivator-rigs and connectedtogether for angular adjustment, a lever carried by the arch-bar, toadjust the members thereof and thereby laterally adjust thecultivator-rigs, and a link, connected to a part of the cultivator andto the said lever to support the arch-barin position,substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

O. M. SULLINS.
